Can Subs and Sub Placement Alter Higher Frequency Sounds?

I have two subs I've been playing around with and I'd swear that switching between them or changing their locations actually impacts non-bass sounds (above my 80hz crossover) This seems especially noticeable with voices for some reason. They will seem more or less boxy depending on which sub I'm using and where it is.

Any reason why this should be or am I imagining it?

Possibilities:

1. The sub will still have significant output well above 80 Hz; it is not an instantaneous roll-off; and,

2. The influence of lower (and higher) frequencies upon our hearing is known and normal. Excess bass, or a lack of bass, can affect our perception of the rest of the frequency band.

Thanks for responding, Don! And good to know it isn't just my imagination, although it sounds like "perception," as you say, plays a role. I've been reading that turning up the LFE channel can in turn drown out midbass, and that may also be what I'm hearing ... will keep tweaking.

Thanks again!
